Vnumaovnlvrrnirr 1N NUT-referenza.

The Schedule referred to in these Letters Patent Aand making part o! the same` To .all whom it may concern l Beit known that -I, MANAssEH ,Gnovnin of-Clyde,

v in the county of Sandusky, and State of Ohio, have invented a new and useful improved mode of constructing what I denominate a ,Nnt-Fastencr, to use or bc p used on reapeis and mowers, and on all other machines l to which it may be adapted, in such a mode as yto prevent the nuts when screwed tight on to the said nutfastener from becoming loose b y turning, or rot-ating backward, or in a direction 'to become loose, (only by pressure whenl desired and'I do `hereby"declare that the. following is a full, clear, and exactidescription of* th'ecoiistruct-ion and operation of 'tliesaine, reference being had to the accompanyingdrawings, and` to the lettersfot' reference marked thereon, making la pai-tof the specification, in which- Figure 1 is, a perspective View 0f the machine, exhibitin g the construction and operation of the said nut fastener. l

y The naturel of my invention consists in a new and improved mode of constructing .what I denominate a nut-fastener,to use orbe used on reapers and mowers, and `on all other machines to which it may be adapted, in such a mode as` to 'prevent .the nuts when screwed tight on to the said nut-fastener from becoming loose by turning or Irotating backwardor in a direction to become loose, (only by pressure when desired.) p l i To enable others skilled in the art to make and use` my invention, Ifwill proceed to describe its construcf l tion and operation.- l l v,

D,as seen in the accompanying drawings, is the main bar to the machine, exliibting the fconstruction and operation of tlevnnt-fastenerA.

S is the bolt, by which means the nut N is screwed tight on to the nut-fastener A. f y a The corners O O of the said nut-fasteners are curved on from the bar D, in order that thel nutN cannot'- turn or rotate backward, thereby becoming loose with;

lout the corners O O of' thenut-fastener A being pressed sutiiciently toward' the bar D, which is done by turningjor rotating thenut'N, which presses its corners against the comers C O of thesaidnutasteuer, `and y,forces them toward the bar D as the corners of the- 'nut N come in contact with the said corners O. C when pressed forward or backward.

` Said nut-fastenerV is constructed of spring steel, or any other suit-able material, and immediately afterthe corners of the said nut N pass over the corners O G of the nut-fastener A, the said corners O C of the said nut-fastener spring back to their proper position, as VSeenatC (l, fig. 2.

,B Bare the two corners-of the said nut-fastener, curved toward the barV D, and placed int-o the indentations at H H, fig. 3, for the purpose of preventing the nut-fastener`A from turning or rotating by pressure when forcing the nut N either forward or backwardv C B, tig. 5, representan end view of the nut-fastside between the corners coucaved a little toward the 1 bolt-hole L, for the purpose of admitting thecorners C O of the saidnutfastener to spring into. To prevent .the said nut from turning ibrward or backward only when desired, the nut-fastener A may have the Iside that. is in contact with the bar D fu'rrowcd or cut similar to a tile, in order to prevent it from turning with nut `N,when it may become necessary to use Ait in places that cannot have indentations made as at H Hf Y `.llihat `Iblaimias `my invention, and `desire to secure bygLettersPatent, is-f` Y i .y'lhcfk `stantiallyfcrl the purpose hereiubeforefset forth.
